A one-pot method for the efficient and simple synthesis of the novel spiro[indoline-pyrazolo[4',3':5,6]pyrido[2,3-d]pyrimidine]trione derivatives by a three-component condensation reaction of barbituric acids, 1H-pyrazol-5-amines and isatins in aqueous media is reported.
Synthesis of novel 1H-pyridazino[1,2-a]indazole-1,6,9(2H,11H)-triones using one-pot, three components reaction of 1,2-dihydropyridazine-3,6-dione, dimedone and aldehydes under solvent-free conditions has been reported. These products were evaluated in vitro for their antibacterial activities.
